makes the message hidden

same with any message that evaluates to false: no, false, 0, etc will send a message that appears blank (and unclickable/unreadable unless you know the message number)

pls fix

Foxie:this is how he can fix it

Foxie:ng-show="m.subject" to ng-show="m.subject===''"

Foxie:or

Foxie:m.subject.length
